Methodology

We recognise commercial real estate’s top agents and firms across the United Kingdom.

Methodology for Determining the Winners of the 2025 CoStar Awards

The following criteria represent the methodology used in generating the CoStar Awards for all categories. Each award is based on transaction data included in CoStar’s commercial real estate database, which is verified and continuously updated by our Research team. As this information is gathered and confirmed daily, totals and rankings could change when new information is obtained. Agents are encouraged to provide information on all transactions closed during calendar year 2024 to ensure they receive full credit for their closed transactions.

The award methodology for all CoStar Awards is subject to change at CoStar’s sole discretion.
